The Lowdown

Alright, grab your wetsuit. We got a mixed bag coming up over the next couple of weeks, but there is some proper grunt in there if you know where to look and when to paddle out.

The main player is Jaconé. It’s exposed and catches the southerly pulses well, and from Tuesday the 11th we get a big wall of energy. The water is sitting at 74°, which is a touch warmer than normal for this time of year—nice.

Tuesday the 11th kicks off with a solid, powerful 10 ft S swell at 13 seconds. That is a lot of water moving—combined energy is massive at 3082. But honestly, this is too much for this break. It will be wild and unruly, and the east wind, while cross-off, won't tame it. That one is for the big-wave chargers only; the rest of us sit this one out.

Wednesday the 12th looks better. The swell drops to a still-pumping 8 ft from the south, period hanging at 12 seconds. Morning session with an ENE cross-off breeze is the go. It is big and powerful, still for the experienced crew, but the energy (1523) is cleaner and more manageable.

Thursday the 13th is actually the standout, in my books. We wake to clear skies, a light 5 km/h NE offshore wind, and a 7 ft south swell. The direction is spot-on, the wind is glassy, and conditions will be clean as a whistle. Energy is still strong at 1343. This is the session to target—early, with the offshore wind, for some proper, lined-up walls.

Friday the 14th to Saturday the 15th sees the swell back off a touch (6 ft to 7 ft) but winds get a bit tricky, swinging onshore or cross. The mornings are your best chance, especially Saturday the 15th morning with that ENE cross-off, but it won't be as epic as Thursday.

Then we hit a bit of a lull. By Sunday the 16th, the swell drops to 4 ft in the morning, and though the wind goes offshore, the energy is down to 613. The wind picks up hard in the afternoon (35 km/h) so it is a short window. Monday the 17th through Thursday the 20th is pretty weak—swell hovers around 3 ft to 5 ft but with short period E windswell (7-8 seconds). There are some okay offshore windows (Monday morning, Tuesday morning) but the energy is low (232-549) and the waves will be small and crumbly. A quiet stretch.

Friday the 21st and Saturday the 22nd are messy—onshore winds, lumpy conditions, and very little energy. Save your gas.

Now, a real highlight appears on the horizon. Monday the 24th of August. We get a new pulse of long-period groundswell from the south, 4 ft at a very long 16 seconds. That period is serious—the energy jumps back to 1435. Winds are light offshore from the ENE. That is a river-mouth or reef kind of day; the long period will make it wall up but might close out on the beach. Tuesday the 25th keeps the grunt going with 6 ft of south swell at 14 seconds and a strong offshore wind (20 km/h ENE). Clear skies, solid energy (2097), and clean conditions. That Tuesday morning is your second big standout.

Wednesday the 26th wraps things up with a glassy morning—5 ft from the south-southwest, 13 seconds, and no wind. The energy is still solid at 1167. A nice, clean finish to the window.

The best of the best:
- Thursday morning, August 13th – 7 ft S swell, clean offshore wind, clear skies. That is the one.
- Tuesday morning, August 25th – 6 ft S groundswell, strong offshore, clean and punchy.

Crowds at Jaconé are *sometimes* an issue. On those standout days, expect company.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
